(creci-reel@ tion of a needle-in the closed-hook position. taken My invention relates tothe artofknittingand Vit more specifically has reference' to the and knock-over sinkersv usedon warp knitting machines.'y n f v PrimarilyA the invention has' forenv object toy providey a needle and, sinker combination which is particularly. adapted for' inr knittixuzma-` chines of the kind disclosed in myvapplication j f serial Number 506,561n1ed October 16, 1943.

Other objects of the invention* are: to provide a knitting needle of such'reinlorced construction 1 that the needles` may be made of exceptionally tine gauge without bending or breaking' under the usual strains and stresses encountered in high-speed warp knitting machines; to "Ovide u.A

needle in which the advantagesof a slide-hook closer are combined with that of a springy beard: to provide va needle of such construction that ng.- s is acrossseeuon on the unes-sof nana. l is a' crois seotion'on'the line 4-0 of Pig-2. FigLis a'vertical section on the line #-l of Pig. lfwiththe needle indotted fline'--position;

' In the drawing, in which likenumeralsfotreff 'erene'eindicate like parts in all the Mures. it will be seenthat the needle asa .whole is composed o! two sections. One of these sections comprises Aa vshankIhavingabase!andanextensiionlota,

reduced thickness. a bend I, and a beard l that liea--ingenerale-parallel with the portion I, the i beard i including the portion l* which closes the when the weakest part of the needle passes through the loop in knocking-over. the loopwill be looser thanwhen it is drawn'about that pari:l

oi' the shank of the needle Iaround which the loop is cast while the opening of the needle is receiving thread or yarn by the action of the thread guides, thereby relieving the needle from strain at its weakest place; to provide a needle in which the springy-beard portion need Alievi: only slightly while the thread or yarnf'is passing out o! the hook; to provide a needlev of such construction that when .pulling a loop through a previously formed loop the Vpull is substantially directed along the length of the needle and the bend o! the hook oi the needle is reinforced by the hookopening closer.

Again. it is an object to provide a sinker with throat or opening of th'e hook. The other oi' the two sections includes' the shank l, having a base l. anextension il o! areducedthickness,abend il, and a portion Il that lies-in general-eparalleltotheportion iIand-whoseendisspaced from rthe shalt to provide the throat opening oi' l the hook, th'at is closable by the beard portion il;

Itwillbeseenthattheportion ilottheinner needle extends a substantial distance' parallel t0 the portion il and is comparatively rigid so that :s a substantialy support means for supporting the needle sidewise and to provide the sinker with a higher knock-over portion than the nib in order to 'make it unnecessary to bring the needle down into the sinker as deeD as heretofore andl thus enable a shorter stroke of the needle to be used in the vknitting process.

Other objects will in part be obvious and in part will bey pointed out' hereinafter.

To the attainment ot the aforesaid objects and ends the invention still further resides in the novel details of construction, combination and arrangement of parts', all of which will be iirst.q fully described in the following detailed descrip-- tion. and then be particularly pointed out in the appended claims, reference being hadvto the uc-v whenthethroatoftheneedlel iscloeodbythe portionotthebearditheportion ilserves or brace lor th'e beard le whllethe thread is being cast about the needie.

'lhe combined -or overall perimeters ot the sh'anks of the two scc tions being greater than the overall perimeter.ot the'hook portions o! the needle, provides means for pulling out the loops so that as the needle knocks over the loops will slip over the hooks easily. f l l In order to provide support for the hook end of y the needle while the thread guide or guides are laying the thread about the needle, I provide the sinker il with a thickened portion II on each blade. thereby brlnging'the support for the needle as near the li'ook endo! the needle as possible at that time.

Inl'ig. ithelulilinesindicatetheneedleinthe raised position with the l thread guides Il and 2i` casting the thread about the needle to enter the throat thereof. In this position ot the needle the throat o! the needle is open; the light dotted linea indicate the needle on its upward journey, slipping the loop L' out o! the hook oi' the needle: the heavier dotted lines show the position of the needle at the lower limit of its stroke in pulling loops L through thepreviously tannedA loop L' at the raised knock-over portion i il o! the suiker.

Any suitable means (not shown) may be provided for positively reciprocating the needle and its separate parts .in harmony with the knitting process, but as such means, per se. is not a part l of the present invention, illustration thereof is thought to be unnecessary. l

From the foregoing description, taken in eo nection with the accompanying drawing, it is thought that theconstruction. operation and ad,-

vantages ot the invention will be clear to those skilled in the art to which it appertains.

What I claim is:

i. A knitting needle comprising two bodies of approximately the same thickness, one embraced by the other, each of said `bodies including a shank and shook-the hook of the inner body having a throat. the hook of the outer body hav- -as a throat closer when the two bodies are closed the shanks and along the front portions only of mg s sprinsy beard including a portion serving u thehooks, the outer one of the hooks having a springy beard portion which extends below the end of the inner one of the hooks when the bends of the hooks yare together, the sh'ank of the section which has the inner hook having a recess releasably to receive the point of the beard when the bends of the hooks are together, the combined perimeters of the shanks ot the two sections being greaterthan the over-.all perimeter of the hook .portions ot the needle. j
